MACHINE FOR FILLING AND LOADING FABRICS.

Application filed November 17, 1924. Serial' No. 750,501.-

Bc' it known that we, .loiiN .latins llAiur soN and Joux \Vii,i.i.v\u Herisau., bothsubjects ofthe King ol' (ii-eat Britain, residing in Manchester, llngland, have jointly invented certain new and useful Improvements in lilachines for Filling and Loading Fabrics, ot' which the following is a specification.

This invention relates to machines for carrying out filling, loading and analogous operations on continuous lengths ot' fabrics, the machines being of a known kind which comprises a vertically adjustable top bowl or roll driven from a maindriving s iaft, a pair of relatively adjustable horizontal bottoni bowls arranged tandemwise and in a manner to be driven from the said shaft in either direction of rotation and so as to convey liquid fil'iing or loading substance from a source of supply or liquor box on the machine. and apply it -to fabric passing vover suitable tensioning devices, and also a number of yieldingly mounted doctor knives, the

bowls and doctors being adjustable in position to permit of the degree or extent to which a'fab'ric is to be loaded being varied.

The invention consists in improved Construction and arrangen'ientof parts as hereinafter described and claimed.

The machine is provided with a pair of starch or other liquor-containing tanks or boxes, which make it possible to cliarge the machine with two different substances,iand allow of additional impregnating or coating processes, as enumerated below, to be carried out simultaneously on one and the same machine.; These boxes, preferably constructed with4 wooden bottom and iron sides, are

mounted in 'a manner to allow themto be l tilted for cleaning and other purposes, and are associated with means whereby they can be rocked or tilted. A roller is provided for guiding the fabric during some processes from one box into the other.

By providing a machine with two liquid containing boxes, the following additional stiffening and filling processes, besides others not illustrated, can be carried out, viz:.

.correlated with the bottom bowls for coilf' trolling the thickness of' the film-ot' starch applied to the cloth and is so arranged that it can be adjusted for either forward or reverse mot-ions as may be necessary in the following processes, double back skimming, single back skimming, back filling, and back filling with back skimming.

A further improvement is that the gear wheel, which is fixed to the shaft carrying the upper bowl and is used to rotate the shaft and. bowl, isdriven, during operations requiring its rotation, directly from a gear wheel keyed to the main driving shaft, in` stead of indirectly by the latter gear wheel through oneor more intermediate gears, as previously proposed.

.One of the main objects of the invention is to produce a machine of the kind referred to which is more compact than has been hitherto the case, which affords an operator or attendant easier access to the parts that need adjustment from time to time and wherein there may be a nearer supervision of the work than what has been customary,

To these ends, the lower bowls and doctors, the tensioning devices and other elements are placed, as compared with known machines, in positions nearer the vertical plane containing the .axis of the upper or squeezing bowl. n

The invention will be described with reference tothe accompanying drawings, in

Fig. 1 is a side elevation of a filling or loading machine of the kind referred to above and embodying the improved construc- 'tion and arrangements, some parts being omitted or broken away.

Fig. 2 is a detail sectional drawing showing a doctor knife and its holder arranged between the pair of lower bowls as indicated in Fig. 1.

Fig.v 3 is a brolien fragmentary sectional plan .view of some parts'shownin Fi 1 tioned herein, and F ig. 1 5'isa dagrammatical view showing the travel ofa length of fabric through thefmachine from the inlet to-y the outlet thereof during.v stifening operation.

a-rietioning and In the drawmefs the referencenumeral l' denotes the top lbowl or roll, and 2 and 3 are the bot-.om :bowls orgrojllsl Thel top bowl l is carried by atransverse shaft 4' :supportedv inbearings, z.one of which is shown at 5 slidably mountedvin anuprig'ht l'ranle 6, which may be', y:is shown -in Figs. 3, ol' channel sectlon andv 1s fixed to a mam base frame '7., The bearings .rare'vert1j cally adjustable in- .upright "guides 8 by means of a pair ofv screwthreaded rods which. are arranged one on either. side o f Y the machine, one being shownv at 9 in Fig. 1. Each of the rods. 9 cooperate with a screwthrcadcd nutldevice formed in a boss'10 on a lever 11 pivoted at one end 12 on supports 13 'on the guide frame 6. -The rods 9'are 4eachvadapted to be turned by means of handwheels 9v. The other ends of the two levers r h' h 11 are, as 1n lnown Amac mes, eac connect v by. operatmg the han (1 -Wheel 9,'

The lowerfrolls 2 and 3 are also drivencd to one end of 'a link v14, which may be adjustable in length and is yat its other endv pivotally attached to a levery 15- which is pivoted at its en'd 16 to a part of the frame 7, and at its other end carries an'- adjustable weight `17. The top bowl 1 is thus 'suspended and, when it meets with' any undue pressure, rises and yields to such pressure and'- return to its normal position when that pressure ceases. f

The bearings 5 mayeac'h carryapointe'r 18 which, as the bearings are raised'or lowjered. passes over graduated markings 1 9 von the frame 6 thereby enabling the bearings` to be' accu1'a tely adjusted? to the; same level.

Means; such asy blocks- 30 adjusted byl studs 30', screwalilei'in position en -theu 4 right fram'e, may-be provided for limiting the movement "of the bearingsl 5 in a downwarddirection. The Vbottom rolls 2and 3 are horizontally -adjustabletowards andjj from one. another,

Byfadjusting the bearings of the spindles inany appropriate manner to the main base frame 7. v

Connected with each block.2l is.' a screw- .,threaded rod 25fthat co-operates with screwthrefads formed in nut fashion in the bored hubof a bevel wheel -26 that meshes with a v similar bevclwheelv 27 carried by a spindle 28 suitably'suppo'rted on a part of the machine fram'ing. v By turning the spindle 28 bynieans of a `hand-wheel 29," or ini any other-convenient way, the block 21 can .be

lmoved along the' guidcway 22 in one direction or the other as may be required.

.The spindle 20- earryin-e' roll 3 is supblocks 21 which are adapted to he moved, in a similar manf ner to blocks2l, along a guidcway 22 between guides 23 on )the fran1e24, by means of thescrew-threaded rod 25 co-operating with nut threads on the bevel wheel 26. in

mesh. with bevel wheel 27 on spind1ef28 ofbowls 1,2 and 3 in positionas described above, either one or two nipping` points' may be arranged betweenthe curved surface-.of

the `bowls or alternatively the three bowls vmay be entirely se arated.

- The top bowl 1 1s driven from-the; main driving shaft 31 which `carries a toothed wheel 32 with which a toothed wheel 32 keyed to the shaft 4 of the bowl 1 can be moved into and outl of direct engagement 'and in n either direction.y The mechanism comprises a pair of bevel'wheels 33 loose on the shaft 31 and in mesh respectively, at diametrically opposite. points, with a bevel wheel -34; on the lowervend' offa verticalv shaft 35 mounted insuitable bearings `on the-'frame 7, and it also includes a clutch device 36 mounted to rotate with shaft 31 andto slide along a' feather thereon.

bymeans ot hand-Wheel The clutch isoperated by means of a two-arm forked appliance 37 which is keyed to a.

spindle 38 carriedby supports 3 9, the arms being yokedto the clutch. The spindle and clutch are controlled by means of a hand,

lever 4 0 which is located at the ront of the machine and is moved vin one direction or the other so that the device 36 clutches one or otherof the bevel wheels 33 according to the' direction'in which shaft '35 35"-carriesa bevel wheel 41 \vhieh gears with a bevel Wheel 42 fixed toa shaft 43 supported at its ends invbearin'gs 44 car- 45 and 45, vand slidubly mounted onv shaft 43 are two bevel wheels 46 and 46 which. by means of mechanisms described below, can he individually moved intoand out ot" engagement with wheels 45 and 45 respectively. Each of said mechanisms comprises` a pair of pins 47 slidably mounted on a supporting block 48 carried by the, shal't 43, by means of a pivoted bearing inside of the respective supporting block 48, and by the. extended portion 20* of shaft. 2t) or 20 as the case may be, traversed by the shaft 43. ,llach pin has a finger 4S) that projects into a. grooved hub 50 or 50 on wheel 46 or 46. Each pair of pins 47 can be slid to and fro by means of yoke pieces 51, slidably mounted on blocks 48 and coupled each to an operating handle 52 pivoted at 52 on the corresponding block 48. ily turning the proper handle 52 on its pivot the wheel 46 or 46 can bc made to engage. with or be disengaged from wheel 45 or 45 resjwctively. 'lhe ends ot' the extended portions Q0* of the shafts 2t) and .20 are, housed in thc adjacent blocks 48 so that when the bearing 2l or '21. is adjusted in position by being moved lengthwise of the. guidcways 22 or Q2', the corresponding block 48 and parts associated with itv will have a corresponding movement. j

The machine as illustrated isprovided with two liquor-containing boxes or tanks 53 and 54. one for each bottom bowl. Means are preferably provided for rocking or tilting these tanks which at their innerends may be pivoted or hinged together as indicated at 55, or in other convenient way. The means for rocking the tanks may consist in eccentrics 56 rotatably mounted in suitable bearings on the frame 7'in a position wherein they bear upon the under faces of the bottoms of the tanks. The ec-centrics may be turned in,their bearings by means of the handles 56'. Each tank may be provided, as is customary, with one or more power driven agitators. In the machine illustrated one such agitator is indicated in each tank at 57.

A doctor-knife 58 is, as is customary in machines of the kind referred to` provided to operate as required between the bottom bowls 2 and The knife 58 and its holder 59, Fig. 2, is detachably fixed in any convenient manner in a. sector-like member 60 that is arranged to turn about a pivot or spindle 61 on a block 62 arranged one on each side of the machine. Each Y,block is connected with a rod 63 by which it can be made to slide up and down abracket guide 64 in known manner, for the purpose of making the knife approach or recede from the cylindrical surface of the top bowl 1. The means for rocking the member 60 with the knife 58 about the pivot 61, so as to vary the knifes inclination to and pressure on the fabric being loaded or treated, comprise, according to the present; invention, a link '65 which is provided at one end with an appropriately lshaped nose (S6 that is arranged to engage in one of two recesses 67. 68 in the sector 6() according to the angle. of inclination at which the knife is held. When the required pressure'of the knife on the fabric is light, the link 65 may he. fixed in various adjusted positions, for which purpose the, end of the link remote from the knife is slotted by which it can be, secured by--means of a pin 65) at varying heights in a slotted bracket 7() supported from the machine frame, the height of the pin connection determining the inclination of the knife 58 to the roll surface. Preferably, two links 65, one on cach side of the machine, would be provided.

lf the required pressure of the knife on the fabric is heavy, the link would not have its outer end fixed or pinned as just described, but would be free to move and there would be suspended from the link 65 ,a suit-able weight. 71vwhich would tend to turn the sector 60 and knife 58 about the pivot 61 so as to cause the knife to irnjmrt. pressure against the fabric when the knife is in operation.

A. second doctor knife72 may be provided in rear of or at the exit side of the bowl 3. This'knife is adjustable in position for the purpose of varying the pressure exerted by it on the fabric being treated or of moving it clear of the same. The knife is, in'known manner, attached to a holder 73 carried by a spindle 74 journalled in blocks v75 slidably mounted in upright frames 76 secured l to the main frame 7, one von each side of the machine. The blocks can be raised and lowered by means of the screwed rods 77 and hand wheels 78, and their inclination to the vertical can be adjusted by means of the member 79 that co-operates with the holder 73.

Associated with the upper bowl 1 there may be a'cleaning knife 80 which can be of rubber and be held in a holder 81 carried by a rocking spindle 82 mounted on a block 83 that is adjustable in position by means of a device 84 in a guideway provided on a bracket 85 fixed to the upright frame 6. Supported by the spindle 82 is a lever or bar 86 that carries a weight 87 that can be adjusted in'position along the bar 86 to vary the pressure exerted by the. knife 8() against bowl 1.

The device provided for controlling thel thickness of the film of starch or other substance applied 4to the vcloth or other material being loaded, comprises a roller 88 of which the shaft is removably and loosely journalled in arcuate grooves 89'forn'1ed in bracket members 90 fixed to the machine frame6, one on each side thereof. The arcui, to occupy ate grooves 89 of the bracket members 90 are concentric with the axis of rotation of the lbowl with which the roller 88 cooperates. Thus the brackets and .the arcuate grooves thereof are so disposed that the roller, when supported by the brackets extends lengthwise labove the bowl with which it co-operates.

such positions being at the two ends of the Aarcuate grooves 89. It would occupy one of those positions when the adjacent bottom v processes.

The cloth fabric or other material to be loaded enters the machine over tensioning rails 93 which ai'e carried by longitudinal members 94 supported by brackets -95 fixed to the frame or frames 6, and in certain loading processes, for instance in double stifl'ening (Fig. 4) also about rails 93 on brackets 100 carried by the frames 24. From the tension rails the material passes about two horizontal bars 96, 97 carried by a frame or part 98 which has journals 99 that engage in bearings provided in the brackets 100. The frame 98 is shown in Fig. 1 in a vertical position, but it can be lplaced at any desired inclination for telisioning purposes by turning it in its bearings and fixing it in adjusted positions by means of a pin '101 that passes through hole in the bracket 100 and projects into one or other of the holes in the circular row 102 on the framev 98;

For the purpose of guiding .the fabric during some of the above-mentioned processes prom one of the two tanks to the other,

a roller 103 is suitably mounted on the ma.

chine framing.

As is usual, a guide roller 104 is provided on the exit side of the machine. The roller is carried by two bearing blocks 105, one on each side of the machine, the blocks being slidably mounted in a bracket 106 supported from t-he frame 7. The blocks can bevraised and lowered by means ot the screwed rod 107 which can be turned by actuating bevel gears 108 controlled byhand wheel 109. Attached to a spindle 110 carried by a bearing block 110 supported ou the member 94 is a draw roller 111 driven by a belt 112 from main driving shaft 31.

As stated above, the diagrams, Figs. 4-14', show the top and bottom bowls 1, 2 and 3 variously arranged for effecting various The roller, when in use, is arranged one of two operative positions,

The arrangement in Fig. 4 is for double stifl'ening. l

The arrangement in Fig. 5 is for single stiffening.

The arrangement in Fig. 6 is for single friction.

The arrangement in Fig. 7 is for double friction.

The arrangement in Fig.'8 is for friction and stifi'ening.

Thearrangementn Fig. 9 is for single padding.

' The arrangement in Fig. 10 is for double padding.

The arrangement in Fig. l1 is for single back skimming.

The arrangement in Fig. 12 is for double back skimming. l

The arrangement in Fig. 13 is for back filling.

The arrangement in Fig. 14 is for back filling and back skimming.

Fig. 15 shows diagrammatically the travel of a piece of fabric or other material 113 through the machine during a friction and stiffening process. The materials supplied from a wagon or batch (not shown), as the case may be, enters the machine over the first tensioning rails 93 and about the other rai1s'93. From the last of these rails it dpasses downwardly about ythe bars 97 an 96 and the rails 93', between bowls 1 and 2-'and between bowls l and 3. Issuing from between bowls 1 and 3, the material passes upwardly to the draw roller 111 around which it travels on its way to plait- *ing or hatching mechanism which is not shown.
